Anyone know what the effect of mud season might be expected to be on the Russian defensive lines? How does the ground turning into a sodden morass affect minefields?

I don't know anything about armor tactics but they seem very confident in Russia's inability to hit any drat thing to send one tank right out into the open like that to assault that treeline

I'm going to assume the Ukrainians had been doing detailed recon on the forces in the treeline and knew exactly what they were and were not equipped with, since they said they had been there long enough to clear routes through the minefields to that forested area.

It doesn't, really, weather doesn't really affect mines, just makes them harder to find.

Huh. Here I would have assumed the MIC would spring for insulated wire in the first place.
They need a lot of wire in a small space, so I could see them going with bare wire just to save volume. If they fixed it, it was probably some electronic wizardry or some super thin lacquer solution.

They must be insulated! Most spools have the wire maximally interacting with itself on the spool!

As long as the wire is only touching itself that wouldn’t matter. It would still only be connecting the missile and the launcher. Just with a large clump of copper/metal on one end. That wouldn’t affect any electrical signal.

That said, if the wire sagging and touching water was a problem, then sagging and touching the ground could also be a problem. However, water is a much better conductor, so I guess leaked current could be a bigger problem there.

I’m mostly just guessing/speculating here. It could also be that they didn’t really consider the water problem too much (or deliberately ignored it) until they later found a good, easy way to fix it or decided it was worth the effort and expense to fix it.

FWIW, you should be able to do it with one wire. You don't need to transmit a (usable) current, just a signal, and for that all you need is a capacitor and relatively high frequency alternating current.

In that situation it could have an effect if the wire is laying in water instead of ground.

According to this source the TOW 2 wire-guided missile has two wires:

quote:

TOW anti-armour missile

The missile has command to line-of-sight guidance. The weapons operator uses a telescopic sight to view a point on the target and then fires the missile. The missile has a two-stage ATK (Alliant Techsystems) solid propellant rocket motor. The operator continues to view and track the target through the sight. Guidance signals from the guidance computer are transmitted along two wires, which spool from the back of the missile to the control system on the missile. The Chandler Evans CACS-2 control system uses differential piston type actuators.

During the great deluge of videos of Syrian armor getting annihilated circa 2015-2017 there are several clips of TOWs being fired where the two wires are visible if you squint a bit.

I couldn't remember it to save my life, but firing a Wire Guided TOW over water requires an algebraic equation. I'm not joking. Fairly certain it details a bit in the publicly available stuff why, but don't want to venture towards OPSEC land.

It's no longer needed with the wireless TOW variants as far as I know.

Dragon definitely did; you had to aim above your target and then dip it down once the missile was past the water. You also had to do that if there was any heavy brush. Dragon was a piece of poo poo, and I hated the fucker.

could the problem have been the physical effects of drag from the very long wires falling into the water rather than electrical effects?

According to this .mil site the problem is explicitly shorting out:

quote:

Firing over bodies of water.

Maximum and limited range firing over water varies by missile type. If the range is less than 1100 meters, the missile’s range is not affected. However, if it is wider than 1100 meters it can reduce the range of the TOW. A TOW position should be as high above and as far back from the water as the tactical situation allows. The squad or section leader should analyze his sector as soon as the position is occupied to determine if water will affect the employment of the TOW. Signals being sent through the command-link wires are shorted out when a large amount of wire is submerged in water.

Every tank has a functional toilet in the turret if you're nasty enough (or if the civilian contractor just signed off on the turn-in documents).

I can't find any one tweet summarizing this, but it looks like the Ukrainians have broken into the Russian's first line of defenses in Verbove and Novoprovopivka, but the Russians are following their plan and regularly counterattacking from the second line of defenses.

How long can either side keep that up for? Will the Ukrainians have to withdraw if they can't stop the Russians from counterattacking?

DJ Burette

The recent trends have been that the Ukrainian's let the Russians exhaust themselves by counterattacking into artillery and then continue onwards, but obviously this relies on you managing to hold off the counter attack. At this point it's probably too early to tell if they will manage to hold onto their forward positions or if there will be more back and forth.

Literal WW1 tactics. We are probably weeks out of tune with what is going on and I figure once they realize what is going on the forward attacking unit will have counter battery fire ready to go already and the Russian tubes presited in on the trench line being attacked will get vaped faster than a ecig in a kombucha lounge.

One of the grimmer bits of analysis from the Royal United Services Institute was, along with a general increase in tactical adaptation from Russian units*, that they have become very good at striking a position immediately as defenders are withdrawing. To the point where Ukrainian units are essentially taking positions and then having to move off them straight away as a fluid part of the assault.

*They assessed that the "lol Russian incompetence" stereotype of the troops on the ground was no longer particularly applicable iirc.

Traditionally, trench assaults always rely on follow on logistics to be taken, because the doctrine of every military ever is to counterattack and deny them the leverage. That counter is most often in the form of an immediate Infantry assault, but could also come from indirect fires.

If the attackers have friends, fires, or supporting elements, they can make an attempt to hold, but it ends up being a scrabble to who can get the most into that little area. That always favors the defenders- their assault troops will always be closer. I don't know the exact math to it, but I know that a BN sized unit would be tasked with assaulting a trench position that would be held by a company size element. A lot of dudes into a narrow hall, hope they get a toe hold, and can keep enough blood pumping for the next wave through.

A good example of this kind of desperate push/pull struggle can be found in 'Hell In A Very Small Place', and other accounts of the Siege at Dien Bien Phu. Particularly the Foreign Legion taking and retaking of one of the smaller firebases that made up the base itself. Not exclusively trench fighting, but a drat good example if you dont want the PTSD of watching GoPro. I mean there are plenty of accounts, but large scale trench warfare after WW2 has been pretty short of choice examples (thankfully for humanity).

A lot of reports lately are that Russia sometimes just leaves destructive charges in the most prepared areas and blows the place once they retreat and it’s overrun.
